Former Bankas Snoras AB owner Vladimir Antonov, who is fighting extradition to Lithuania to face fraud charges, lost a U.K. court ruling to lift a freeze of his assets and delay a related civil lawsuit.

Vladimir Antonov , the Russian investor who helped finance Spyker Cars NV’s purchase of Saab Automobile, is in talks with General Motors Co. to become a shareholder in Saab, Svenska Dagbladet reported, citing Antonov.

Latvia is seeking to recover about 150 million lati ($290 million) from Vladimir Antonov, formerly the majority owner of Latvijas Krajbanka AS’s parent bank, which was suspended by regulators because of missing funds.
